Compared with the traditional mode that a plurality of tunnel lamps are connected, in the embodiment, the connecting lug 910 is directly arranged on the end cover 90, the mounting hole 920 is formed in the connecting lug 910, and then the plurality of tunnel lamps are connected by penetrating the mounting hole 920 between the fasteners such as screws. This kind of mode need not to use other connecting piece 620 to carry out the auxiliary connection in the junction of two tunnel lamps, only needs to utilize itself just to carry out interconnect with the end cover 90 that needs to use, and the connection structure of simplification tunnel lamp that can be very big simplifies the installation procedure of tunnel lamp, reduces the use of mounting, alleviates the weight of tunnel lamp, the fixed mounting of the tunnel lamp of being convenient for.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
